Abstract
The utility model provides a mining flame-proof switch, comprising a cabinet body, a wiring cavity and a main cavity. The switch is characterized in that a control transformer, a disconnecting switch, a near-far control switch, a vacuum contactor, an electronic protector and a current transformer are arranged in the main cavity; and a handle, a stop button and a starting button are arranged on one side of the cabinet body, wherein the handle is used for connection and disconnection of the disconnecting switch or commutation. The mining flame-proof switch replaces a traditional magnetic contactor in an actuating current of 2.5A with the vacuum contactor in the actuating current of 0.38A; since the actuating current of the vacuum contactor is about 1/6 that of the magnetic contactor, enameled wires for the control transformer matching with the vacuum contactor are changed into 0.38mm and 1.25mm wires, and a coil of the control transformer matching with the vacuum contactor uses copper wires whose weight is 0.7 kilogram; and the weight of the vacuum contactor is 0.45 kilogram less than that of the magnetic contactor. Through tests, each performance parameter of the rewound control transformer can meet national standards of related technology, thereby eliminating the phenomenon that a previous transformer is burnt for insufficient capacity.
Description
Technical field
The utility model belongs to Mineral Product Flame-Proof Switch and transforms the field, especially relates to a kind of Mineral Product Flame-Proof Switch.
Background technology
The contactor that QBZ series Mineral Product Flame-Proof Switch (80.120.200) uses, the Magnetic contactors that adopt more, its attract current is 2.5A, supporting transformer is with 0.55mm and two kinds of lines of 1.5mm with it, coil adopts copper coil, weight is 2.3 jin, and not only weight is large, and easily burns because transformer capacity is not enough.
The utility model content
The purpose of this utility model provides that a kind of overall weight is light, transformer capacity is large, eliminated the Mineral Product Flame-Proof Switch that transformer in the past burns because of off-capacity.
The technical solution of the utility model is: a kind of Mineral Product Flame-Proof Switch, comprise casing, wire connection cavity and main chamber, and it is characterized in that: be provided with control transformer, isolating switch, far and near control switch, vacuum contactor, electronic protector, current transformer in the main chamber; Casing one side is provided with handle, stop button, start button, and handle is used for disjunction and isolating switch or commutation are closed in the pass.
Further, described a kind of Mineral Product Flame-Proof Switch is characterized in that: described casing is processed by Plate Welding.
Further, described a kind of Mineral Product Flame-Proof Switch is characterized in that: described vacuum contactor, attract current are 0.38A.
Further, described a kind of Mineral Product Flame-Proof Switch is characterized in that: described vacuum contactor, supporting control transformer enamelled wire is 0.38mm and 1.25mm with it.
Further, described a kind of Mineral Product Flame-Proof Switch is characterized in that: described vacuum contactor, and supporting control transformer coil is copper cash with it, weight is 1.4 jin.
Advantage and the good effect that the utlity model has are: overall weight is light, transformer capacity is large, has eliminated the phenomenon that transformer in the past burns because of off-capacity, has guaranteed product quality.

Embodiment
The below is elaborated to preferred embodiment of the present utility model.
As shown in Figure 1, the utility model provides a kind of Mineral Product Flame-Proof Switch, comprise casing 12, wire connection cavity 10 and main chamber 9, it is characterized in that: be provided with control transformer 8, isolating switch 7, far and near control switch 5, vacuum contactor 3, electronic protector 2, current transformer 1 in the main chamber 9; Casing one side is provided with handle 6, stop button 4, start button 11, and handle 6 is used for disjunction and isolating switch 7 or commutation are closed in the pass.
Further, described a kind of Mineral Product Flame-Proof Switch is characterized in that: described casing 12 is processed by Plate Welding.
Further, described a kind of Mineral Product Flame-Proof Switch is characterized in that: described vacuum contactor 3, attract current are 0.38A.
Further, described a kind of Mineral Product Flame-Proof Switch is characterized in that: described vacuum contactor 3, supporting control transformer 8 usefulness enamelled wires are 0.38mm and 1.25mm with it.
Further, described a kind of Mineral Product Flame-Proof Switch is characterized in that: described vacuum contactor, and supporting control transformer 8 coils are copper cash with it, weight is 1.4 jin.
The attract current that the utility model has been abandoned using in the past is the 2.5A Magnetic contactor, using attract current instead is the vacuum contactor 3 of 0.38A, because the attract current of vacuum contactor 3 is about 1/6 of Magnetic contactor, so supporting control transformer 8 usefulness enamelled wires are used 0.38 and 1.25 lines instead with it, the coil copper cash, weight is 1.4 jin, compares Magnetic contactor and reduces 0.9 jin.Control transformer 8 various performance parameters of again coiling all can reach national relevant technologies standard-required after tested, have eliminated the phenomenon that control transformer 8 in the past burns because of off-capacity.
Above an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
